Application filed October 29, 1919. Serial No. 334,358.

To all 'wlom t may concern:

Be it known that I, SANFORD L. OLUETT, a citizen of the United States,residing at Troy, in the county of Rensselaer and State of- New York,have invented new and useful Improvements in Collars, &c., of which thefollowing is a specification.

Reference may be had to the accompanying drawing, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

This invention relates to collars and other buttonholed articles; theprincipal object of the invention being to reinforce and strengthen thecollar or other article at the end of the buttonhole which is subjectedto pulling strain in use.

Other objects will appear in connection with the following description.

The common expedient of inserting transverse bar-stitches at the end ofa buttonhole, while having some utility, is greatly lacking inefliciency and causes the buttonhole when it finally gives way to ripand tear at right angles to the length of the buttonhole along the lineof the bar-stitches, and after reaching the end of the barst-itches therip or tear generally continues in the direction of the line of pull.

In carrying out my invention, I employ bar-stitches extendingdivergently on opposite sides of the buttonhole at the end subjected topulling strain, said stitches preferably being interlocked at their apexwhereby said bar-stitches act in the manner of a truss to transmit thepulling strain upon the end pf the buttonhole to the threads of thefabric on opposite sides of the buttonhole at a substantial distancefrom said end; and the tendency of the fabric to tear transversely atthe end of the buttonhole is overcome.

The single ligure of the drawing shows on an enlarfred scale abroken-away portion of a collar provided with a buttonhole made inaccordance with my invention.

Referring to the drawing wherein the invention is shown in preferredform, l is the brokenwaway end of a collar provided with a buttonhole,2, formed by cutting through the plies of the collar.

This buttonhole is bordered on opposite sides by thel usual buttonholestitching 3.

Adjacent to the end of the buttonhole which is subjected to the pull ofthe collar button in use, bar-stitches, 4L, are inserted in the articleextending divergently on opposite sides of the buttonhole.

These bar-stitches are preferably made to overlap each other andinterlock at their apex as shown.

Bar-stitches applied in this manner serve not only to directly resistpulling strain in directions substantially perpendicular to thebar-stitches, but they act much in the manner of a truss to distributedirect pulling strain applied at the end of the buttonhole along theline of the buttonhole, to the threads of the fabric on opposite sidesof the buttolhole at a substantial distance from its en I haveascertained by practical demonstration that a buttonhole made in thismanner is able to resist a much greater pulling strain, and morerepeated pulling strains, than an ordinary bar and buttonhole, or than abuttonhole having a bar at its end extending horizontally 0r obliquelyover one side only of the buttonhole.

I have shown the divergent bar-stitches at one end only, the other endof the buttonhole which is not subjected to pulling strain having theordinary transverse barstitches, 5.

It will be understood however, that the divergent bar-stitches can beapplied to either end or both ends of the buttonhole as may be founddesirable.

lVliat I claim as new and desire to secure by Letters Patent isl. Abuttonholed article having adjacent to an end of the buttonhole,bai-stitches extending divergently on opposite sides of the buttonhole,said bar-stitches being interlocked with each other at their apex.

2. A. buttonholed article having the usual buttonhole-stitches borderingthe buttonhole-opening, and having at one end of the buttonholebar-stitches extending diver'- gently on opposite sides of thebuttonhole, said bar-stitches being interlocked with each other at theirapex.

In testimony whereof, I have hereunto set my hand this tenth day ofOctober, 1919.

SANFORD L. OLUETT.
